Why can't i play game (mobile legends) on my phone at school?

The school wifi doesn't seem to be that bad. I installed an vpn on my phone and turned it on. It had the wifi icon and vpn icon, but after a second it both disappeared. Then i tried without the vpn, it wouldn't work. I tried using my mobile data (1.25gb) still wouldn't work. Is it because of the game?... show more The school wifi doesn't seem to be that bad.
